Attack on U.S. mission in Benghazi – Attackers set the U.S. mission in Benghazi, Libya, on fire on September 11, 2012. The U.S. ambassador to Libya, Christopher Stevens, and three other U.S. nationals were killed during the attack. The Obama administration initially thought the attack was carried out by an angry mob responding to a video, made in the United States, that mocked Islam and the Prophet Mohammed. But the storming of the mission was later determined to have been a terrorist attack.

Story highlights

The FBI is expected to question a suspect in the deadly attack on the U.S. consulate in Benghazi, Libya, "in the coming days," according to a U.S. government official with direct knowledge of the investigation.

The United States first became aware of Ali Ani al Harzi when he apparently posted details of the attack on social media while it was happening.

At the request of the United States, Turkish officials detained al Harzi when he entered that country after leaving Libya. Turkey then transferred him to Tunisia, where he is being held.

"We are very pleased the Tunisian government is working with American investigators to allow in person access to Ali Ani al Harzi. Under this arrangement the interviews will be under Tunisian supervision and consistent with their sovereignty and meets the needs of our investigative team," U.S. Senators Lindsey Graham and Saxby Chambliss said in a statement Saturday.

"Allowing American investigators in person access will make the interview more meaningful and is a welcome breakthrough in our efforts to find the perpetrators of the Benghazi Consulate attacks," they added.

A testy exchange erupted between Sen. John McCain and Joint Chiefs Chairman Gen. Martin Dempsey during the latter's testimony about September's deadly attack on the U.S. diplomatic mission in Benghazi, Libya.
